... Figure 15. Reset Timing Diagram MANUAL RESET INPUT The ADM823/ADM825 feature a manual reset input ( MR ) which, when driven low, asserts the reset output. When MR transitions from low to high, reset remains asserted for the duration of the reset active timeout period before deasserting. The MR input has a 52 kΩ internal pull-up so that the input is always high when unconnected ...

... NEGATIVE-GOING V TRANSIENTS CC To avoid unnecessary resets caused by fast power supply transients, the ADM823/ADM824/ADM825 are equipped with glitch rejection circuitry. The typical performance characteristic in Figure 12 plots V transient duration vs. the transient mag- CC nitude. The curves show combinations of transient magnitude and duration for which a reset is not generated for 4 ...
